Abstract: In order to objectively ascertain the stress state of a user and prevent post-partum depression, biological gas information, representing a user dimethyl adipate concentration acquired by a sensor that detects dimethyl adipate released from the surface of the skin of the user, is acquired over a network. Information indicating an upper limit of a normal range for the dimethyl adipate concentration per unit of time is retrieved from memory that stores information including the upper limit of the normal range. When it is determined, on the basis of the biological gas information acquired during a pregnancy period of the user, that there is a tendency toward an increase in the frequency with which the dimethyl adipate concentration of the user per unit of time exceeds the upper limit of the normal range, information pertaining to the stress of the user is outputted to an information terminal of the user.

Abstract: In the present invention, an actual graphic pattern (20) is formed on an actual substrate (S) by lithography based on an original graphic pattern (10). An assessment point setting unit (110) sets assessment points on the original graphic pattern (10), and a feature amount extraction unit (120) extracts feature amounts (x1 to xn) indicating features of assessment point positions. An optimal correction bias estimation unit (130Z) estimates an optimal correction bias (z) indicating an assessment point position correction amount that is required in order to bring the actual graphic pattern (20) close to the original graphic pattern (10) on the basis of the feature amounts. The estimation is performed with the use of learning information (LZ) obtained from a learning stage that has been performed in advance. A pattern correction unit (140Z) performs correction for moving the positions of the assessment points of the original graphic pattern (10) on the basis of the optimal correction bias (z), and creates a corrected graphic pattern (35). This corrected graphic pattern (35) is used to perform lithography.
